GregV: I have timezone set to auto, but after the upgrade it puts my phone to CET (UTC+1). Had to set timezone manually. 2degrees
On 2 Degrees also, had same timezone issue, initially didn't notice it as it was just am instead of pm.
Trying to disable / re-enable network provider settings didn't solve, so yeah, on manual time setting for now.
I also think battery consumption has gone up, but no hard stats to prove.
Didn't have major SD card issues, it just unmounted mine automatically, and once remounted it's working fine.
On a positive note I do like the ETA until full battery when charging. Highly useful.
